iaas_reconfigure_nat

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety bar is lower, but the description adds nothing: it does not say whether the supplied natRules replace the entire existing rule set (a destructive-looking overwrite for an operation flagged non-destructive), whether the call is synchronous, or what permissions are needed. For a mutation with a nested rule-list body this leaves the key behavioral question unanswered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short, but the three lines are largely self-duplicating — the first two lines both say "reconfigure ... nat" and the third repeats the annotation title verbatim. Nothing is front-loaded that helps an agent decide or invoke, so the brevity reflects thin content rather than efficient phrasing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a nested-body mutation with no output schema, and the description says nothing about the replace-vs-merge semantics of natRules, response behavior, or required state of the target Compute Nat. Given the complexity of the body and the write operation, the description is well short of what an agent needs.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the nested natRule properties are richly documented with defaults (kind, protocol, sourceIPs, ports, targetLink), so the schema carries parameter meaning. The description contributes no additional parameter context, making the baseline 3 correct.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

"Reconfigure operation for nat" largely restates the tool name, and "Day-2 reconfigure operation for nat" only adds the vague lifecycle term without saying what is actually reconfigured (the NAT rule list). The POST path duplicates the annotation title instead of clarifying the effect, and nothing distinguishes it from siblings like iaas_create_compute_nat or iaas_delete_compute_nat.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this versus creating/deleting a Compute Nat, no prerequisites (e.g., needing an existing Compute Nat ID), and no mention of when reconfigure is appropriate. The agent must infer everything from the HTTP path.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
